loop in query for view  how to aggregate?
I use the below formula for a view and a dMC. Yet, it will only return the last record i, not all of them. When I create a button to alert all i, it will prove the loop works correctly. How does the view/dMC aggregate all i?
let my_event := this;
let my_entries := this.'is testified by'.entry;
let my_benefices := (select Benefices);
for n in my_entries do
let my_benefices_n := (select Benefices where testimony.entry = n);
for i in my_benefices_n do
i
end
end

This formula below works for the current case  but is a loop in such a formula really impossible to use?
let my_entries := this.'is testified by'.entry; select Benefices where cnt(testimony[contains(my_entries, entry)]) > 0

If you want to see what the script really returns, put it in a formula field, and put the "for" loop inside a "debugValueInfo()" function. You will see that it does not return an array, but an array of arrays…

You may want to look at this post to compare two arrays.

I didn't put clearly enough what I'm after. I need something like pandas.DataFrame.explode in python  to flatten an array of arrays.
The post posted by will go some way towards a solution, I feel.
In my formula above, I get 3 irecords for n=1 and 2 irecords for n=2 (if my_entries returned only two records), for example, so my "view" should aggregate all 5 records.

So you want to end up with records in Benefices where the entry equals the entries of the current record?
Wouldn't this work?
let my_event := this; let my_entries := unique(this.'is testified by'.entry); for n in my_entries do select Benefices where testimony.entry = n end

Arrays of arrays are strange objects in Ninox. They sort of exist, since they can be produced by loops, but they act strangely when one tries to manage them by the usual functions. To flatten such a beast, if you are sure that the values of the elements never contain a comma, you can try:
split(join('Input array of arrays', ","), ",")

thanks! I will check out both solution on the weekend, and mark this thread as answered!
